A grande cup of Starbucks coffee contains 75% of a person’s daily allowance of caffeine, according to data collected by Chemical and Engineering News (CEN). Starbucks denies these findings, saying a grande beverage only contains 140 mg.

Caffeinated bevvies have long been the go-to drinks for those looking to perk up energy or alertness. According to the American Food and Drug Agency (FDA), at least 8o% of adults in the U.S. enjoy a caffeinated drink every day.

But research from Health Canada says a healthy dose of caffeine for the average adult is 400 mg per day. Unfortunately for coffee lovers, the 16-ounce size of Starbucks coffee contains 330 mg — about 75% of Health Canada’s recommended daily dose of the stimulant.

PepsiCo said it doesn’t consider Kickstart to be an energy drink, noting that it still has far less caffeine than drinks such as Monster and Red Bull and none of the mysterious ingredients that have raised concerns among lawmakers and consumer advocates.

But Kickstart, which comes in flavours such as “energizing orange citrus” and “energizing fruit punch,” could nevertheless give the company a side-door into the fast-growing energy drink market without getting tangled in any of its controversies.

It also comes in the same 16-ounce cans as popular energy drinks made by Monster Beverage Corp., which also offers options with juice content.

Simon Lowden, chief marketing officer for PepsiCo’s Americas beverages, says the idea for Kickstart came about after the company learned through consumer research that Mountain Dew fans were looking for an alternative to traditional morning drinks such as coffee, tea and juice.

Kickstart was developed independently from a Taco Bell breakfast drink last year

“They didn’t really see anything that fit their needs,” he said.

Lowden said Kickstart was developed independently from a Taco Bell breakfast drink introduced last year that combines Mountain Dew and orange juice.

With the growth of energy drinks such as Monster and Red Bull expected to slow, Kickstart could also signal the emergence of a new category that plays off the promise of energy and other health benefits, said John Sicher, publisher of the trade journal Beverage Digest.

In a nod to the growing concerns about sugary drinks, for example, Kickstart also uses artificial sweeteners to reduce its caloric content to about half that of regular soda; a can has 80 calories.

“It’s a very interesting experiment capturing a number of attributes,” Sicher said, likening it to Starbucks’ Refreshers drinks, which promise “natural energy” from green coffee extract.

PepsiCo and the Coca-Cola Co. have largely watched the growth of energy drinks from the sidelines

The promise of “energy” has been a big seller in the beverage industry in recent years, with the energy drink market increasing 17% in 2011 even as broader soft drink consumption has continued to decline, according to Beverage Digest. PepsiCo and the Coca-Cola Co. have largely watched that growth from the sidelines, however, with players such as Monster Beverage and Red Bull dominating the market.

But the surging popularity of energy drinks has also led to sharper scrutiny. This summer, New York’s attorney general launched an investigation into the marketing prices of energy drink makers including Monster and PepsiCo, which also makes Amp. Lawmakers and consumer advocacy groups have also called on the Food and Drug Administration to investigate the safety of the high levels of caffeine in energy drinks for younger people.

Although Kickstart may look like an energy drink, it has far less caffeine, at 92 milligrams for a 16-ounce can. A comparable amount of regular Mountain Dew would have 72 milligrams of caffeine while a can of PepsiCo’s Amp energy drink has 142 milligrams, according to the Center for Science in the Public Interest.

By comparison, a 16-ounce cup of Starbucks coffee has 330 milligrams of caffeine.
